VERTICAL CHAMBER OVEN.

Original application filed February 6, 1922, Serial No. 534,627. Divided and this app1icaton filed February 20, 1924.

VT 0 all whom t may concern.'

Be it known that I, CARL O'r'ro, a citizen of the Republic of Germany, whose address 'is I-Iellerup, Sundvey 14, Denmark, have invented certain new and useful Improve ments in Vertical Chamber Ovens, of which the following is a specification.

The invention refers',` to vertical chamber ovens with horizontal heating lines and particularly Vto those in which both gas and air are preheated by the waste heat fof the ovens inseparate, special and individua-l recuperators, or preheaters, this application being a division of an applicationled by me February 6, 1922, under Serial Number 534,627. In the present application the invention relates to a double vertical oven.

The -'preheating chambers for gas and air jare arranged in the prolongations of the horizontal heating llues iforming axial eX- tensionsfthereof andi are lacedv within 'the ovens, in advance of the narrow sides of the oven chambers. rl."he heating llues are arranged one above the other'. Each is connected at one end with a preheating chamber of two compartments, one for air and the other for gas, and with a waste heat chamber at the other end. At each front of the oven the waste heat chambers alternate vertically with the preheating chambers, so that the preheating chambers lie between the waste heat chambers so as to receive heat from the latter. The waste heat chambers and the preheating chambers form recuperators. The lues which form the heating walls are straight and eX- tend along the long sides of the oven chambers. The flow of the heating gases in alternate heating flues, the one lying above the other, passes in opposite directions. The

direction of the flow remains constant. ItV

is not reversed.

In the drawings I have shown the invention as applied to double vertical ovens:

Fig. l is a vertical section on line N-O of Figure 2. Y

Fig. 2 is a transverse section, ,one on line P--Q and the other on line R-S of Figure 1.

In the invention as shown in the drawing, in Figures l and 2, a are the vertical oven chambers with the heating nues b forming the heating wall placed between them. The lues b form each one straight flue which extends along the en- Seral No. 694,102.

tire length of the long sides of the oven chambers. At one end of each flue, forming a prolongation or axial extension of the flue, is arranged a gas preheating chamber o and an air preheating chamber d at theother end the waste heat cham.- ber 6. Gas is continuously supplied at f and air at g. The gas preheating compartmentlies between the two branches of the air preheating compartment. The waste heat from the waste heat chambers is discharged thru vopenings Wand lues i to the staclrflue la For each two superposed iiues the location of the chambers is inter'changed. The heating lues are thus alternately connected in the vertical direction at each front of the oven to an air and gas preheating chamber and to a waste `heat chamber. The airv and'gas preheating chambers are thus located between vtwo waste heat chambers.

The very simple construction and easy 4accessibility of all parts Vof the new systemallow an exact 'and easy Vregulation in all parts of the oven, andl in consequence land preheating chambers for gas and air connected to each heating flue at one front of the o-ven an-d a waste-heat chamber connected to each heating flue near the other front of the oven, the preheating chambers lying between the waste-heat chambers so as to receive heat from the latter.

2. In vertical chamber ovens in whichthe oven chambers are arranged in rows, the combination of heating walls` between the rows, there being a heating wall common to two r-ows of oven chambers, each wall comprising a series of superposed heating flues, each running the whole length of the common heating wall, preheating chambers for gas and air connected to each heating flue at its front end and a waste-heat chamber 4 other end, and a plurality of vertical waste- Vheat Y lines connectedV with the wasteheat chambers, the wastefheat chambersand Vthe preheating chambers alternating at each front of the oven, so that the preheating chambers lie between the waste-heat chambersso as to receive heat from the latter.
